Design
Self-contained design with built-in air cylinder. Air ports are located on the side of the chuck body for stationary use.

Application
OD and ID chucking for milling, drilling, inspection, or any other non- rotating application requiring high concentricity and/or close workpiece roundness. The inherent spring characteristic of the diaphragm allows workpieces to be clamped without continuous air supply for pallet and tombstone applications.
